Pro-choice groups have described the religious ambush of health reform – which this month pressured the House of Representatives to effectively block women from using medical insurance to pay for abortions – as one of the most serious threats to abortion rights of recent years.

Meanwhile, the murder of prominent abortion doctor Dr George Tiller at his Kansas church in the summer added fresh impetus to the US abortion debate.

So, what are the numbers? Despite - or maybe because of - the political importance of the debate, they're not clear. Compiled by the US Centers for Disease Control they only go up to 2005, and there is some doubt over whether later ones will be published. The report itself only has the tables images, ie, they can't be copied unless you type them out.

Well, that is what we have done, just with a couple of tables - total figures and a breakdown by state. There are some omissions. California, the most populous state in the union, does not compile (or release) abortion figures. But this is what there is. Let us know what you can do with it.
